What is the angle of incidence of a ray of light if the reflected ray is at an angle of 90° to the incident ray?
ScienceClass 8ICSEAnswered 28 Mar 2026
Answer
The angle of incidence= angle of reflection.
Given i+r= 90 degree i=r, i+i=90 degree 2i=90 degree.
I=45 degree.
Therefore, the angle of incidence is 45 degree.
